1N5266

Single Zener Diodes Overview

The 1N5266 is a unidirectional voltage regulator diode manufactured by SMC Diode Solutions. It features a nominal Zener voltage of 68 V and a maximum power dissipation of 0.5 W. The device utilizes silicon planar technology and is housed in a glass DO-35 axial leaded package. Standard Zener voltage tolerance is ±20%, with tighter tolerances available via specific suffixes such as 'A' for ±10% or 'B' for ±5%. The component supports an operating junction temperature range from -55°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using silicon planar technology within a compact glass axial package.
• Offers standard ±20% Zener voltage tolerance with optional tighter precision variants available through manufacturer suffix codes.
• Designed for high thermal stability with a maximum junction temperature rating up to 175°C.

Single Zener Diodes Applications

• General purpose voltage reference circuits
• Overvoltage protection stages
• Biasing networks in analog signal processing

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix required for the application, as the base part number denotes a standard ±20% tolerance while tighter specifications require distinct ordering codes. Confirm RoHS compliance status and packaging format availability directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected variant meets the required thermal and electrical specifications for the target environment.

Single Zener Diodes Selection Notes

Select this component when a reliable 68 V reference is needed in a standard axial package. Consider tighter tolerance suffixes if circuit accuracy demands less than ±20% variance. Verify that the 0.5 W power dissipation rating aligns with the expected current draw and ambient thermal conditions of the final assembly design.

Single Zener Diodes Part Context

This component belongs to the 1N52-series of 500 mW Zener diodes produced by SMC Diode Solutions. This series covers a wide voltage range from 2.4 V to 200 V in the DO-35 glass package. The 1N5266 specifically addresses applications requiring a 68 V regulation point within this standardized family of axial-leaded regulators.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5266 designation. Verify pinout compatibility and ensure equivalent power dissipation and voltage tolerance ratings are met by any substitute part before implementation.
